ADDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 756,706, dated April 5,1904.

Application filed December 22, 1903. Serial No. 186,212- (No model.)

To aZZ whom it may concern.-

Be it known that'I, WILLIAM P. QUENTELL, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented new and useful Improvements in Adding-Machines, ofwhich the following is a specification.

This invention relates to adding-machines; and the invention resides innovel features of construction set forth in the following specificationand claims and illustrate din the annexed drawings, in which Figure 1 isa plan view of a machine embodying this invention. Fig 2 is a sectionalong m m, Fig. 1. Fig. 3 is an inverted plan view of Fig. 1. Fig. 1 isa section alongyy, Fig. 5 shows a form of stylus. Fig. 6 is a plan Viewof a portion of a disk-on a larger scale than the preceding figures.Fig. 7 is a section along 2 2, Fig. 6. Fig. 8 is a section along a .2,Fig. 6.

The machine comprises a number-disk a, which carries numbers up to anydesired denomination. have been found to be a practical arrangement. Aframe or support is shown at Z). This support can be of any suitableshape or construction, such as box or open-work. A plate, as

shown in the drawings, will answer. The buttons or legs 0 for thesupporting-plate when made of rubber will not be apt to slip when thedevice is manipulated. This frame 5 has a sight-opening at d, throughwhich one or another of the figures of disk (0 is exposed as the latterrotates. The pivot e of the rotary disk is supported by a strip orbridge-piece f. The

opening 9 in the frame I) has lip or part g, forming a zero-stop, aspresently explained. The disk is partly exposed through this opening g.The disk has a perforation or seat at h for the insertion of a stylus orlike instrument, Fig. 5, by which the disk can be rotated or set toZero. When the stylus is arrested by stop g, the figure 0 shows at sightd. About the circumferential portion of disk a are holes or catches i.The frame or support has a slot at is. This slot is shown running alongor exposing a number of said holes a. The holes shown are a cheapconstruction;

The figures from O to 99 but other means, such as corrugations orshoulders or other catch portions for a stylus to take hold, can beemployed.

Guides m are shown leading into slot 10. These guides/might be calledbranch slots of the trunk or main slot is. These guides are shownnumbered from 1 to 9. For spacing and convenience of selection theoddnumbered guides can be placed on one side of the slot and the evennumbers on the op posite side. The guide numbered 9, for example, is atsuch distance from the stopping-point of the slotthat is, the end of theslot just past guide 1 -that when a stylus or the like is inserted intothe hole 71 at such guide 9 and the disk is rotated, as shown by thearrow, by moving the stylus to rotate the disk until the stylus isstopped at such stopping end of the slot such disk has advanced ninenumbersthat is, the number now showing through the sight d is ninehigher than the number last preceding at the sight. Similarly bystarting at another guide, as 8 or 5, the disk is rotated or advanced acorresponding number in each case.

The stylus can be a rod of metal or a pencil, or other instruments mightbe made to answer.

The guides-m are of such size or enlarged at their ends that the styluscan be readily inserted therein and then run along to slot is to engageinto the required seat or hole 2'. As these holes are small and closetogether, mistakes are liable to occur when inserting the stylus intothese holes direct; but errors can be easily avoided by previouslyinserting the stylus in a guide.

In addition to guides k the disk may have guides or grooves 0 branchingfrom holes a, so that a stylus will be guidedboth by guide m and bygroove or channel-guide 0 to enter the required one of the holes 2'. Theguides or grooves 0 are readily formed by depressions in the top or faceof the disk, giving the under side or face of the disk a wavy orcorrugated appearance. The sheet metal forming the disk is suflicientlythin or flexible to allow this deflection or corrugation.

The under side of disk 64 is held from bending or supported at an edgeportion by a plate 01, having an offset or portion which while allowingthe entry of the stylus into a hole a certain distance at the same timesuitably limits such insertions.

A stop or under plate 7) at perforation it limits the entry of thestylus at this point, so that when rotating the disk to the zero-stopthe stylus cannot project and strike the bridge f, whereby mistakesor'premature stoppage might be caused.

A counter is shown at q in form of a hand pointing to a series offigures or a dial-say 0 to 7. 1n the example shown this counter is almndreds-counter. If, for example, the disk should show a figure, sayS0, at the sight (Z and the hand q point to 2, a total of 280 would bethus indicated.

The hand 9 is connected to a gear or segment 1' by pivot s, which is ashoulder-screw. A spring 25 gives a friction to prevent accidental shiftor rotation of the hand. A pin a connects the hand and gear, so thatthey swing together. This pin a projects into a slot in plate 5, wherebyits movement or swing can be limited between certain points-for example,O and 7 in the example shown. In moving its figure 99 along past sight(Z plate a by tooth 4; moves gear w one step to set the hand (1 alongone figure. WVhen the disk a is set to zero, the tooth e is in suchposition that the gear 1' can be moved back to Zero, which is done bythe operator moving hand 9 to zero.

' Suppose three columns of figures are to be added up. The first orright-hand column or units are first added by successively inserting thestylus into the guides respectively corresponding to the successivefigures in the column and rotating the disk the required orcorresponding extent by moving the stylus each time to the lowerterminal of the slot. If such first or unit column should add up to 103,the hundreds-counter stands at 1 and the disk shows the figure 3 atsight (Z. The figure 3 is then noted or put down by pencil or the likewith a memorandum of ten to carry. The disk and counter are then bothset to zero. To the next column is then first added the amount carried,say ten, which is made to appear at sight (Z by moving plate a bysuccessively actuating from guide 9 and guide 1. Then the figures insaid next column are successively noted. Suppose the total of the secondcolumn is a8. Such sum will now appear at sight (Z. Putting down the 8leaves four to carry to the third column. The parts a and g are thenagain set to zero. Noting the next or third column of figures plus four,or the amount earriedgiving, for example, 56 the grand total will be a5683.

A stylus 11 is shown with a cap or pencil engaging part to be adaptedforapplication to a pencil; but the invention is not limited to any specialform of stylus.
